You are more trusting than I am.Also the bus bars are from amazon, however they said they could take up to 250 amps

Same inverters and battery setup , starts my old definitely non energy star rated 2.5 ton mini split with no issues. I have the battery cables that came with the Batts as well. My batteries tie to a bus bar individually, then bus bar has 2/0 wire to each inverter, via appropriate ocpd.Yes it runs great. It’s pulling about 1500 watts on each inverter. My A/C will not work and I’m assuming it’s because I need to install a soft start. It’s only a 2 ton system, I figured this setup would run it no problem.
Is the fault code 61 still gone?Follow up after trouble shooting the split phase configuration on the EG4 6500-EX inverters. During the initial inverter setup I used a single string of solar panels to power the first inverter while changing the settings, then I disconnected the panels and powered up the second inverter to perform its setup. However, when I powered each inverter with its own solar array, programmed them together, performed a shutdown and restart of the system, they both came online together. This appears to have been the issue. Both inverters are currently running split phase with no issues. Thanks for those who have their input and for all on the forum, it’s a wealth of information. Hopefully this will be helpful to anyone with this system.
I doubt it.Isn’t there a shunt in the inverters?
Sorry I missed that detail. I am following a thread on 61 and Richard said he has another.The fault code 61 is gone because on inverter setting #5 I selected user instead of EG4. If you select EG4 it will be there until signature solar can come up with a fix.
Good to know, thanksFWIW with the err 61 i had this as well - the battery comm cable was going the wrong direction. If you look at the rj45 connectors the one that goes into the inverter should only have 2 wires on it. its kinda flimsy looking end but i taped mine - once i did this err 61 went away
your DC wires are far too long. I would try to keep everything from inverter to battery under 3 ft!Here are the pictures of my setup. I’ve scrolled all my setting on both inverters and they both have the exact same settings except for 2P1 and 2P2.
It should run no problem! Unless…you left program 28 in default phase (120*)Yes it runs great. It’s pulling about 1500 watts on each inverter. My A/C will not work and I’m assuming it’s because I need to install a soft start. It’s only a 2 ton system, I figured this setup would run it no problem.
